system upgrade from F28 to F31: problem with installed package NetworkManager-libnm

[Frédéric]

Hi,

I would like to upgrade a system from F28 to F31. But I get the following error:

 Problem: problem with installed package
NetworkManager-libnm-1:1.10.12-3.fc28.x86_64
  - package NetworkManager-libnm-1:1.20.10-1.fc31.x86_64 conflicts
with NetworkManager-glib < 1:1.20.10-1.fc31 provided by
NetworkManager-glib-1:1.10.12-3.fc28.x86_64
  - package NetworkManager-libnm-1:1.20.4-1.fc31.x86_64 conflicts with
NetworkManager-glib < 1:1.20.4-1.fc31 provided by
NetworkManager-glib-1:1.10.12-3.fc28.x86_64
  - NetworkManager-libnm-1:1.10.12-3.fc28.x86_64 does not belong to a
distupgrade repository
  - problem with installed package NetworkManager-glib-1:1.10.12-3.fc28.x86_64
(try to add '--allowerasing' to command line to replace conflicting
packages or '--skip-broken' to skip uninstallable packages)

--allowerasing does not seem to be a nice option. In particular, I do
not have a physical access to the computer so if I loose the network,
it will be difficult to recover.

Any idea what I can do?

Thanks,

F
